5. الإعداد والتثبيت
يُعد التركيب الصحيح أمراً بالغ الأهمية لأداء المحرك وطول عمره.
5.1 التركيب
- The motor features a B3 frame, indicating foot mounting. Ensure the mounting surface is flat, rigid, and capable of supporting the motor's weight and operational forces.
- Use appropriate bolts and washers to secure the motor firmly to the base. Check for proper alignment with the driven equipment to prevent excessive vibration and premature bearing wear.
5.2 التوصيل الكهربائي
يجب أن يتم تنفيذ جميع الأعمال الكهربائية بواسطة كهربائي مؤهل.
- مزود الطاقة: Connect the motor to a 220-240 V AC, 50 Hz single-phase power supply. Ensure the circuit has adequate current capacity (9.85 A nominal) and is protected by a suitable circuit breaker or fuse.
- التأريض: Properly ground the motor frame to prevent electric shock.
- اتجاه الدوران (مع عقارب الساعة/عكس عقارب الساعة): The motor supports reversible rotation. Refer to the wiring diagram provided on the motor's terminal box cover for instructions on how to change the rotation direction (Clockwise/Counter-Clockwise). Typically, this involves reconfiguring the capacitor connections or main winding leads.
- الوصلة الطرفية للكابل: Use appropriate cable glands to ensure a secure and sealed entry for power cables into the terminal box, maintaining the motor's ingress protection rating.
